Description

Technical Field

[0001] This utility model relates to the field of winding devices, and more specifically, to an automatic correction tension control device for label rolls. Background Technology

[0002] During the production of label rolls, take-up rollers are used for winding. Typically, multiple take-up rollers are used in the winding device to achieve the winding purpose. Patent publication number CN222293088U provides a hot melt adhesive film rewinding device with precise tension control and automatic correction functions. It includes a frame on which an unwinding assembly, a drive roller group, and a take-up assembly with automatic correction function are arranged sequentially, and is equipped with a controller. The unwinding and take-up rollers are driven by unwinding servo motors and take-up servo motors respectively, while the slide for correction is driven by a servo cylinder. The controller connects the unwinding servo motor, the take-up servo motor, and the tension sensing roller to form a closed-loop tension control system. The controller is also connected to the correction sensor and the servo cylinder to form an automatic correction control system. This invention can quickly and accurately adjust the tension of the hot melt adhesive film and the offset error of the roll end face, ensuring the consistency of the hot melt adhesive film tension and the flatness of the roll end face throughout the rewinding process, significantly improving product quality. It belongs to the technical field of polymer hot melt adhesive film winding device.

[0003] In existing technologies, the aforementioned winding device monitors the surface of the roll material using a correction sensor during winding to achieve immediate correction. However, this device only corrects the deviation at one end and is positioned between two winding rollers. If the surface of the roll material on the opposite side folds, it cannot be detected immediately if the detection surface remains unchanged. Furthermore, because it is positioned between the winding rollers, when the detected plane changes, a section of the winding distance is already compromised. Consequently, this section will fold during subsequent winding operations, affecting the overall winding effect. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an automatic correction tension control device for label rolls. It can detect the deviation of the roll being transported on the roller in the first instance, and thus correct the roll in the first instance. By applying lateral tension to the roll and changing the position of the roller itself, a dual correction effect is achieved, thereby improving the correction quality and ensuring the integrity of the roll transportation.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] An automatic correction tension control device for label rolls includes a U-shaped frame. A slider is fixedly installed at the bottom of the U-shaped frame. An electric slide rail for electric sliding is provided on the outside of the slider. A mounting frame is fixedly installed on the top surface of the U-shaped frame. A roller is rotatably installed inside the mounting frame. A drive gear is fixedly installed at the outer end of the roller. A correction device is fixedly installed on the outer side of the top of the mounting frame. A detection and adjustment device is movably installed above the mounting frame.

[0009] Furthermore, the detection and adjustment device includes a double-grooved screw, with rotating wheels fixedly installed at both ends of the double-grooved screw. A connecting frame is rotatably installed inside the outer side of the rotating wheel, and the other end of the connecting frame is fixedly installed on the outer side of the mounting frame.

[0010] Furthermore, a transmission plate is threaded onto the surface of the double-threaded screw, a support rod is fixedly mounted on the inner side of the bottom end of the transmission plate, a detection plate is fixedly mounted on the outer end of the support rod, a correction sensor is fixedly mounted on the bottom of the detection plate, and the support rod is movably sleeved inside the mounting frame.

[0011] Furthermore, the detection plate is configured as a curved plate, the curvature of which matches the curvature of the roller. There are two correction sensors, which are located on the left and right sides of the bottom surface of the outer end of the detection plate, respectively.

[0012] Furthermore, the correction device includes an electric telescopic rod one, one end of which is fixedly connected to a connecting seat, and an electric telescopic rod two is fixedly installed on the side of the connecting seat. An arc-shaped block is fixedly installed on the outer end of the electric telescopic rod two, and a correction arc block is fixedly installed on one side of the arc-shaped block.

[0013] Furthermore, one side of the electric telescopic rod is fixedly installed on the outside of the mounting frame, and a silicone layer is integrally formed on the outer edge of the correction arc block.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) This solution uses a detection plate in conjunction with two correction sensors to detect the plane integrity of the roll material transport on the roller surface in real time, thereby determining whether the roll material on the roller surface has shifted or stacked in the first time, which improves the correction efficiency. Furthermore, the overall position of the detection plate can be shifted to change, thereby further improving the overall correction device's ability to adapt to the transport of roll materials of different widths.

[0017] (2) This solution utilizes a correction device in conjunction with an electric slide rail to change the shape in real time based on the results detected by the correction sensor. This achieves the dual correction effect by pulling apart stacked rolls and changing the horizontal position of the rollers for rolls with overall positional deviation. Furthermore, the control process is simple and the operation is easy, further improving the practicality of the device. Attached Figure Description

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Example 1:

[0028] Please see Figure 1-4 An automatic correction tension control device for label rolls includes a U-shaped frame 1, a slider 2 fixedly installed at the bottom of the U-shaped frame 1, an electric slide rail 3 for electric sliding of the slider 2, a mounting frame 4 fixedly installed on the top surface of the U-shaped frame 1, a roller 5 rotatably installed inside the mounting frame 4, a drive gear 6 fixedly installed at the outer end of the roller 5, a correction device 7 fixedly installed on the outer side of the top of the mounting frame 4, and a detection and adjustment device 8 movably installed above the mounting frame 4.

[0029] It should be noted that the electric control between the slider 2 and the electric slide rail 3, the visual detection of the correction sensor 807, and the overall electric adjustment of the correction device 7 in this application are all centrally controlled and adjusted by the controller. The control operation of the controller is a mature existing technology and a predictable technical means. Therefore, this application will not elaborate on this in detail.

[0030] The detection and adjustment device 8 includes a double-threaded screw 801. Rotary wheels 802 are fixedly installed at both ends of the double-threaded screw 801. A connecting frame 803 is rotatably installed inside the outer side of the rotary wheel 802. The other end of the connecting frame 803 is fixedly installed on the outer side of the mounting frame 4. A transmission plate 804 is threaded onto the surface of the double-threaded screw 801. A support rod 805 is fixedly installed on the inner side of the bottom end of the transmission plate 804. A detection plate 806 is fixedly installed at the outer end of the support rod 805. A correction sensor 807 is fixedly installed at the bottom of the detection plate 806. The support rod 805 is movably sleeved inside the mounting frame 4. The detection plate 806 is shaped as a curved plate, and the curvature of the curved plate matches the curvature of the roller 5. There are two correction sensors 807, located on the left and right sides of the bottom surface of the outer end of the detection plate 806, respectively.

[0031] Specifically, the connecting frame 803 provides limiting support for the rotation of the rotating wheel 802 and the double-threaded screw 801 as a whole, ensuring that they can rotate in place without any deviation from other positions, thus ensuring the transmission movement of the transmission plate 804. Secondly, the support rod 805, which is sleeved inside the mounting frame 4, also limits the threaded transmission between the transmission plate 804 and the double-threaded screw 801, ensuring that it can only move the detection plate 806 in a single axis. By matching the curvature of the detection plate 806 with the curvature of the roller body 5, the detection position of the correction sensor 807 is more closely aligned with the plane curvature of the roll material transported on the surface of the roller body 5, thereby improving detection efficiency.

[0032] The correction device 7 includes an electric telescopic rod 701, one end of which is fixedly connected to a connecting seat 702. An electric telescopic rod 703 is fixedly installed on the side of the connecting seat 702. An arc-shaped block 704 is fixedly installed on the outer end of the electric telescopic rod 703. A correction arc block 705 is fixedly installed on one side of the arc block 704. One side of the electric telescopic rod 701 is fixedly installed on the outside of the mounting frame 4. A silicone layer is integrally formed on the outer edge of the correction arc block 705.

[0033] Specifically, electric telescopic rod 1 701 and electric telescopic rod 2 703 are used to adjust the position of the correction arc block 705 in two directions, so that it can adapt to the transportation needs of rolls with different elongations and has the correction effect on stacked rolls. The silicone layer material structure can reduce the surface damage of the roll during the correction process and prevent damage such as tearing of the roll.

[0034] The working principle of this utility model is as follows: The existing drive mechanism and drive gear 6 are connected in an adaptive manner to drive the roller 5 to rotate. The detection position of the correction sensor 807 is adjusted according to the transport width of the roll material. The double-grooved screw 801 is rotated to drive the transmission plate 804 to move to the appropriate position and stop. Then, if the roll material is deviated during transport but does not stack, the controller controls the electric slide rail 3 to drive the slider 2 to change the horizontal position of the roller 5, thereby changing the force point of the roll material and achieving the purpose of correction. If stacking occurs, the controller controls the electric telescopic rod 703 to pull back, which drives the correction arc block 705 to pull the surface of the stacked roll material accordingly, thereby applying external force to flatten the stacked part. It should be noted that the electric telescopic rod 701 needs to be adjusted at the beginning of the transport process so that the silicone layer of the correction arc block 705 is just attached to the surface of the transported roll material.

[0035] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
